STAMPING DEVICE.

' Specification of Letters Patent.

' Batented July 9, 191%.

Application filed-January 20, 1917. Serial No. 143,495.

To all whomz't may concem:

. Be it known that I, FRANK E. ANDERSON, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city of New York, and State of- New York, have invented certain new and useful Improvements in Stamping Devices, of which the following is a specification.

My invention relates to stamping-devices, especially to those in which the type-face or printing-surface is formed of soft-rubber; and my said device, herein disclosed, is of an exceedingly simple and cheap form of construction, easily operated, and self-inking; and while not limited to such use, as shown, described and claimed herein, it is so formed and constructed as to be especially adapted for use in stamping upon eggs, the dates of insertion in cold storage, etc., or other de-- sired data; such dating, especially, being now required in several States by law or regulation, before such eggs can be placed in storage.

My said invention is fully shown and described in the following specification, of which the accompanying drawing, forms a part, wherein similar letters or numerals of reference designate like or equivalent parts,

wherever found throughout the several Fig. 2, is a side view thereof looking from v the bottom of Fig. 1, in the direction of the arrows; and

Fig. 3, is a front view of the stamp-block, in central vertical section, taken on substantially the central line 33 of Fig. 1, looking toward the right in the direction of the arrow; and

Fig. 4, shows diagrammatic views of the stamp-block, (and inking-pad) in five dif ferent relative positions marked A, B, C, D

and E.

Referring to the drawing:

The reference numeral F designates a suitable base-piece of wood or metal, to which is pivotally mounted the stamp-carrying rock-lever composed of the double-bar rear ether so that the two will rotate in unison by a pin 21, or in any other desired manner, such cam-shaft 5, having formed integral therewith at one side, the throw-cam 6, of

substantially the shape shown having the rounded ends 6 and 6 and the concavities or retaining faces 18. The journal ends 22, and 22 of the shaft 5'- extend beyond the block and throw-cam as clearly indicated in Figs. 2 and 3; which ends spring into position in suitable journal perforations formed in the ends of the yoke L, as clearly shown in Figs. 1 and 2, where it will be revolubly held by the natural resiliency of the sidepieces 3 of such yoke.

The stamp-block G is usuall and preferably of the form shown in etail, and in central longitudinal section in Fig. 3, comprising the central cylindrical main or bodyp'ortion 10, having the smaller diametered, like cylindrical stamp-holding end portions 11,.usually and preferably provided with the annular stamp-securing exterior-grooves 12. And such end extensions 11 are each provided with a concavity 13; which concavities into the grooves 12 of the block 10. The

face 14, of the concavity, i provided with a date or any other data, lint in this case, to indicate the type-face molded in the rubber, I have used the word eggs. The central rear securing cavity of the stamp, formed by the flanges 15, of the rubber printing-face of the stamp, is of a slightly smaller diameter than are the cylindrical holding ends 11, of the stamp-block, so that when placed in position thereon, as clearly indicated in Figs. 2, 3 and 4, such stamps will-be held in place upon either end of the stamp-block G by the natural resiliency ofios ' side, usually the one with such annular soft rubber securing flange 15 and; the cooperation-of the heads 30 with the grooves 12.

The yoke-lever L and L has attached to the rear the lift-spring 18, secured at the I bottom to the screw or other pin 1'7, secured in the end of the base-piece F, so as to maintain the forward end of the yoke-lever carrying the stamp G, in the raised, ready for printing, position shown in Fig. 2, and in Fig. 4 at A.

i The throw-cam 6 is of practically figure exterior form, being provided with rounded ends 6 and 6" and stop-faces 18,

concaved as shown, in which fit the convex outer-end front stop-face 19, of the campawl 7 immediately above the throwhook 20.

The head-portion 19 and '20 of the throwlever 7 passes up within the yoke on either shown, as indicated in Figs. 1 and E2; and is held in position against the throw-cam 8, by a suitable coil or other spring 23, secured at the other end to a screw 2%, in the block F, all as clearly indicated in Figs. 1 and 2.

Secured in position usually in a cavity formed in the base-block 1*, immediately below the stamp-block G, is an inking-pad.

it, usually of the well-known rubber-stamp self-inking type.

Rubber-stamp faces I and l are as before indicated in this type of apparatus used "for marking eggs; slightly concaved; so as to fit the contour of the side or end of the egg, to be marked; and such stamps of my improved form, are usually placed in front of the candler, and adjacent to the candlinglamp; and one of the faces, which are oi? course identical, having been inked, and the stamp-block given a half revolution, the candler then candles the egg, and quickly presses the side thereof down into the concaved top flexible rubber printing-head surface 14: of the top printing face I, as indicated by the dotted lines in Fig. 2; and this pressing the stamp down upon the inking pad K, when the under printing stamp 1, comes in contact with such inking pad; and sudic'ient pressure is brought upon the egg to imprint the legend upon I thereon, this forces inward the top concave printing surface 14;, and the consequent compression of the air in the concavities 13, connected by the central air passage 13' will tend to force the face of the bottom rubber-type member I outward into a convex form, as shown in dotted lines in Fig. 3, upon the ink-pad K, which, is usually of the rounded form shown and the same will be consequently thoroughly inked.

When in the raised position, and inked ready for operation, the throw-pawl 7, is in the position shown in Figs. 2 (and a at A) he, securing front-face 19 in contact earse-e with the rear concaved-face 18, of the throwover the same as clearly indicated at B;

and upon the release of the stamp-block G from pressure of the egg; the yoke, by the action of the spring 16, will, by the quick movement of the cam-pawl exerted on the cam, throw the printing-block G, a half revolution to the rear, intothe position shown in Fig. 1, such motion and action and the various positions assumed by such stamp-clock, throw-cam and throw-pawl during such reversal, all being clearly indicated in Fig. 4-, whereby the just inked bottom-pad ll will he brought to the top to receive the next egg, while it, will be in position to he inked upon the printing of such egg, and this operation is repeated indefinitely whereby a much greater number of eggs may be candied and stamped than by the devices now used in a given time.

The upward throw oi the stamp is limited by the contact of the stop-pin 25, yoke-lever L, against the rear of the bracket 2, as clearly indicated in Figs. 1 and 2.

lit is evident that many changes and modifications in the construction 01" my improved stamping device, and many of the parts thereof, may be made, without departing from the scope of my invention; and I do not intend to limit myself to the exact struction of the parts thereof herein shown.
